I ran the 570s in a 95 in twin cam in a fuel injected, 1999 Road King for over 60k miles. Compression was 9.7-1. Heads were ported and flowed, stock intake, evo exhaust valves, S&S springs, roller rockers. White Brother's 2-1 E pipe, S&S VFI computer. Make 98 HP and 108 lbft torque. I absolutely loved the performance!
Same bike is now up to 116", S&S setup. The S&S .625 cams didn't work in a bike this heavy. Believe it or not, I run woods TW6HG cams. I loose on the topend but make over 100 lbft almost off idle. The power comes on STRONG at about 2100 rpm.

 

Any body have the website for woods cams? Thanks for reply in advance. I have an Ultra with 113" installed, have se 203 cams in it right now. Had planned on doing a 95" and put the 203's in first, then decided to go 113'. ran out of money real fast, Also the heads are stock with maching done to fit the pistons and get compression down, Is 10-2. Any suggestions on cams for better low & midrange, Right now dyno is 95 hp/114torque. plan on having head work (bigboyz) when I install cams. Thanks againg.

 

I talked to Dan at NRHS performance and he suggested the S&S 570g cam with their Axtell 97 inch Twin Cam kit. I am switching togears and sending them my heads to get ported. Is there anything else I might need to purchase? (06 fatboy)

If you're going to have Big Boyz do your heads, you should really get a cam recommendation from them.

 

I can vouch for that... they rock my world

 

We use them with oustanding results.
Just completed a 88"er that we installed an S&S 4 3/8" crank, bored the cylinders to 107".
S&S G carb w/Thunderjet/.570's/D&D Fatcat/our heads/10.0 cr.
On our dyno it went off at 118 plus hp/122 ft/lbs, SAE.
The measured, or also refered to as actual, was 122/126.
Smoooooooooth, broad power, that the client was VERY impressed with.
